Testing PIO support for RP1 chips on Pi 5 Computers

Ladyada tasked Jepler with exploring the new libPIO for Raspberry Pi 5 computers: this gives us access to the RP1 chip so that we can run custom PIO state machines on the GPIO pins. A common use case is NeoPixels, because of the tight timing requirements of the WS281x LEDs. Here is our first light test that shows it is possible…

Raspberry Pi 5 / RP1 chip support for Neopixels with Python bindings coming soon 🎉💡🖥️🌈🐍

Hot off the PIO-presses, our resident Jepler created a Python binding for the Raspberry Pi 5 that lets us use the RP1 chip
